Susan Sarandon has revealed to Closer that her expectant daughter, Eva Amurri Martino, will be delivering the Oscar-winning actress’s first grandchild at home.

“Eva’s going to deliver at home, so it’ll be a very theatrical event,” Susan told Closer.

The mom-to-be is expecting her first child (a baby girl!) with husband Kyle Martino and joined her mother to gush about the pregnancy to the magazine. “[The baby’s] not coming until the summer, but we’re ready!” she said.

Susan, who has three children of her own, reminisced about her time as a pregnant woman. “It’s such a sci-fi happening!” she explained.

“When you’re pregnant, it seems surreal until the baby’s there.”
